IMPROVEMENT IN FELLING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 119,814, dated October10, 1871 antedated September 25, 1871.

To all 'whom it may concern:

Beit known that I, CHARLES C. BLAKEMORE, of Zanesville, in the county ofMuskingum and State of Ohio, have invented certain Improvements inSewing-Machine Attachments, of which the following is a specification:

This invention relates to a device for seaming and felling cloth, andmay be attached to any ordinary sewing-machine; and consists inproviding a plate of metal forming by its convolutions a double folder,enabling two pieces of cloth or material to be seamed and felled at thesame time and by the same operation, the edges being folded and united,forming a double-lock seam, which will be fully understood by referenceto the accompanying drawing, of which the following is a description.

Figure lis a perspective View, showing the. feeding' end of the helnmerand feller. Fig. 2 is another perspective view, showing the opposite endof that shown in Fig. l. Fig. 3 is another perspective view with the endcut off at the line .fr a'. Fig. 4 is a section view of the front end,with dotted lines representing the cloth. Fig. 5 is a section ofthe rearend, with the cloth folded in front of the needle.

' In Figs. 1, 2, 3 the guards t are omitted to Y show the position ofthe plates forming the device.

A isthe seamer and feller, made of one piecetions of the metal makingthe double folders a a interlocking, as shown in Figs. l and 4. Aportion of the plate marked c and lying between the folders au is cutaway, as shown in Fig. 3, to

allow the folded edges of the overlap to come in contact within thefeller, and the material. so folded leaves the feller as shown in Fig.5. The two lips at the egress or rear end of the feller, and just infront of the needle, are formed by converging the folders c a', asshown. The plate C being cut away allows the parts c a to be broughtnearly together, or close enough to determine the width of seam. t' t"show the relative shape of the folders on the line a' x. r r' show thefolders at the exit end of the instrument. t t are guards attached tothe upper and lower folders a a to assist 'm gathering and folding theseam.

The convolution of the folders c c where the cloth enters is sufficientto allow the cloth to be easily gathered and folded as it passes throughthe convolutions converging from 'c cf to r r', the exit end, where itis passed under the needle, as shown in Fig. 5. The feed of the machinedraws the folded edges of the cloth snugly across the inner edges of theplates r r', and prevents the cloth from wrinkling or gathering, and itis consequently passed through the instrument and across the path of theneedle snugly and evenly folded, dispensing with the elasticity of thefolding blades usually employed.

Having described my improvement, what I claim in my invention is As anarticle of manufacture, the seamer and feller herein described,consisting of the scroll A made of a single piece of metal, all as setforth.
